FIG. 2 is an internal block diagram of the camera-integrated magnetic recording / reproducing apparatus shown in FIG. According to FIG. 2, the broadcast signal input through the antenna 10 (hereinafter, including the signal diverged from the separation type camera described in FIG. 4) is applied to the broadcast signal receiving unit 11. The broadcast signal receiver 11 is tuned at the frequency of the input signal, and applies the tuned signal to the demodulator 12.

The demodulation unit 12 demodulates the signal tuned by the broadcast signal reception unit 11 into a video signal and an audio signal, and then provides the demodulated signal to the first input terminal X1 of the input signal selection unit 13. The input signal selection unit 13 receives a signal from the external signal input unit 14 (for example, through a video / audio jack) through the second input terminal X2, or outputs an output signal of the camera unit 15 that processes a signal captured by the camera 3. The signal is received through the third input terminal X3.

Therefore, the input signal selector 13 selects one of the signals applied to the first to third input terminals (X1 to X3) according to the logic state of the control signal AB output from the microcomputer 16. . Here, the input signal selection unit 13 outputs the video signal and the audio signal to the microcomputer 1 respectively.
It is desirable to be composed of two multiplexers that can be selected by 6. The signal selected from the input signal selection unit 13 is applied to the signal processing unit 18 through the automatic gain adjustment unit 17 and maintained at a constant signal level.

The recording head 20 and the reproducing head 22 are provided for recording and reproducing on a magnetic tape (not shown). Further, the video signal processing unit 18 applies the signal-processed signal to the video signal amplification unit 23 to directly output it to a television or a monitor (composite video signal), or converts it by the RF conversion unit 24 to receive it as a broadcast signal. And output to a TV set (TV signal). This operation will be described more specifically later.

The present invention allows a minimum of three inputs to be selected. That is, a normal broadcast signal (or a video signal and an audio signal modulated to a broadcast frequency) is tuned by the broadcast signal receiving unit 11 and demodulated by the demodulating unit 12, and then an input signal selecting unit 13 is used as a video signal and an audio signal. Is input to the input terminal X1. On the other hand, the external signal input unit 14
Then, a normal video signal and an audio signal are directly connected and input from a general A / V device, or are input from a special device that produces a video signal and an audio signal. Then, in the camera unit 15, the image information converted into an electric signal through the lens 32 (see FIG. 1) and the audio signal input through the capacitor microphone 30 (see FIG. 1) are applied to the input signal selection unit 13.

At this time, the input signal selecting section 13 is the microcomputer 1
According to the logic state of the control signal AB of No. 6, the input signal is selected as shown in Table 1 below.

[0022]

[Table 1]

As can be seen in Table 1 above, the control signal is "A
When B = LL ”, the input signal selection unit 13 selects the broadcast signal, when“ AB = LH ”, the external input signal is selected, and when“ AB = HL ”, The camera signal is selected, and Fig. 3 is a detailed block diagram of the camera unit 15 shown in Fig. 2. According to Fig. 3, the sound input from the capacitor microphone 30 is amplified by the microphone amplifier 31 to be an audio signal. Then, the subject information obtained through the camera lens 32 is converted into an electrical signal by the image pickup device 33 and then provided to the preprocessor 34. The preprocessor 34 correlates the electrical signal. Sex double sampling (Correlated Dou
After performing ble sampling (CDS) and automatic gain adjustment (AGC), the video signal can be output together with the amplified audio signal by providing it to the camera video signal processing unit 35.

FIG. 4 is a schematic block diagram of a camera-separated type magnetic recording / reproducing apparatus. The camera 3 of FIG.
0 and a transmitting antenna 41 are added. The camera 3'is attached to an arbitrary place so that a video signal and an audio signal can be transmitted to the magnetic recording / reproducing apparatus main body 1 '. The magnetic recording / reproducing apparatus shown in FIG. 4 has the same configuration as that of the apparatus shown in FIG. 2 except that it is constituted by a separate camera 3 '.

Therefore, the camera-integrated type magnetic recording / reproducing apparatus applied to the present invention can be equipped with a camera integrally as shown in FIG. 1, and a separate camera as shown in FIG. There is an advantage in that it can be installed in a place so that the signals photographed by the integrated camera shown in FIG. 1 and the separated camera shown in FIG. 4 can be recorded on a magnetic tape or monitored as a TV. If multiple separate cameras are provided, they can be used as surveillance cameras.

If the monitoring function of such a camera-integrated magnetic recording / reproducing apparatus is expanded, a data interface between the apparatus for transmitting or receiving an image will be possible.
For example, when a doorphone is combined with a magnetic recording / reproducing device with a built-in camera, a prerecorded message such as a message indicating the absence of the user can be output and a message of the visitor can be stored. Then, the transmission signal of the image telephone can be recognized to perform the image automatic response function.

Further, a motion sensor for detecting a moving object in a predetermined space is further integrated, and the camera-integrated magnetic recording / reproducing apparatus can automatically photograph a moving object and outputs a specific message stored in advance. You can also continue,
An example will be described. First, a message storage / output device of a camera-integrated magnetic recording / reproducing device having an automatic response function and its method will be described with reference to FIGS. FIG. 5 shows an embodiment of a message storage / output device using a camera-integrated magnetic recording / reproducing device according to the present invention, and FIGS. 6 and 7 are a two-way call device shown in FIG. 3 shows a specific example of the above. Here, the same reference numerals are used for the same configurations as those in FIG. 2, and the description of the duplicated configurations and operations is omitted.

Referring to FIG. 5, a two-way communication device 100 such as an image telephone or a video doorphone is a general term for devices capable of two-way communication between a caller, a visitor or a specific third party and a user. Is. In particular, it is desirable that the present invention be used with a two-way communication device that transmits image signals as well as two-way voice signals. Two-way telephone 10
A signal indicating a call attempt that is generated when a signal is received from 0. A two-way call device 100 to which a call attempt detection unit 110 that recognizes a dial tone of a telephone or a doorbell sound of a video doorphone is connected is not shown. Signals are transmitted and received through. The call attempt detecting unit 110 is connected to the microcomputer 516.

The microcomputer 516 outputs a selection control signal to the multiplexer 513, and the multiplexer 513 outputs to the AGC 17 an output selected from a large number of input signals. In the multiplexer 513, the broadcast signal is input to the first input terminal X1, the external signal is input to the second input terminal X2, the signal of the camera unit 15 is input to the third input terminal X3, and the fourth input terminal X4. Is connected so that the output signal of the two-way communication device 100 is input.

The multiplexer 513 selects the output signal according to the selection control signal AB of the microcomputer 516 as shown in Table 2 below.

[0031]

[Table 2]

Here, the selection control signal of "HH" selects the bidirectional telephone 100 input to the fourth input terminal X4,
The remaining selections are as shown in Table 1 above. The microcomputer 516 controls the signal processing process and output of the video signal processing unit 18, which is controlled according to the user's function selection and software program. Then, unlike FIG. 2, the image signal of the video signal processing unit 18 is input to the memory 130. The data input / output of the memory 130 at this time is performed by the microcomputer 5.
It is controlled by a read / write control signal output from 16. The output data of the memory 130 is connected so as to be input to the bidirectional telephone 100.

In FIG. 6, a ringing signal sensing unit 113 is configured as a call attempt sensing unit, and the same components as those in FIG. 5 use the same reference numerals. In this structure, the functions to be used in the present invention, that is, the functions necessary for automatic response are the function of outputting a message stored in advance according to the ringing signal detection and the function of storing a signal input through the image telephone. . At this time, the message in the function of outputting a message stored in advance is to make a specific call attempter recognize that he / she is absent or unable to call.

First, the operation of outputting a message stored in advance according to the first detection of the ringing signal will be described. In order for such an operation to be performed, the message regarding absence or telephone call failure should be stored first. As a result, the microcomputer 616 outputs the'HL 'selection control signal AB to the multiplexer 613, and the multiplexer 613 thereby selects the signal output from the camera unit 15. The output signal of the multiplexer 613 is processed by the AGC 17 and the video signal processing unit 18, and a write control signal is output to the memory 133 so that the output signal of the video signal processing unit 18 is stored in the memory 133.
The microcomputer 616 controls to output the signal processed by the video signal processing unit 18 to the memory 133. On this occasion,
The memory 133 is preferably composed of an image memory large enough to store a moving image and an audio signal.

The signal stored in the memory 133 is a message that informs the user that he / she is out or cannot talk. A concrete example is something like "please leave a message because I am out now" or "please leave a message because I will sleep until 6 o'clock". This method is similar to that of a conventional automatic answering telephone. Once the message is stored in the memory 133, the user can program the microcomputer 616 to perform the automatic response function, if necessary.

When performing the automatic response function, the microcomputer 616 checks the signal input from the ringing signal sensing unit 113. When the ringing signal is input, the microcomputer 616 outputs a read control signal to the memory 133 to output the memory 133.
The message stored in is output to the image telephone 120. Therefore, the visual telephone 120 outputs the recorded message to the caller through the cable not shown.

After the above operation is performed, the microcomputer 616 outputs the selection control signal AB as "HH" to the multiplexer 613 to store the input signal from the caller.
Select and output the output signal of. Then, the signal selected from the multiplexer 613 is processed by the AGC 17 and the video signal processing unit 18, input to the recording control unit 19 and magnetically recorded by the head 20, so that the microcomputer 616 processes the control signal by the video signal processing. Part 18
Output to.

Therefore, if the specific user confirms the message of absence or call disabled stored in the memory 133 and sends a signal to leave the message, the signal is transmitted to the image telephone 120, the multiplexer 613, the AGC 17, and the like.
Magnetic recording is performed through the video signal processing unit 18, the recording control unit 19, and the head 20. In this way, the automatic answering function can be performed, and the same operation can be performed again after a predetermined time for the message of the specific call attempter elapses.

FIG. 7 shows a configuration of a video doorphone 140 having a connecting telephone as a two-way telephone. When installing a general video doorphone, a video doorphone camera for confirming the visitor at the entrance (camera with a microphone capable of processing image signals and audio signals)
And a speaker for outputting a user (landlord) voice signal, and a bell key for generating a bell signal.

The one provided in the house is equipped with a display device for confirming the image of the visitor, a microphone, and a number of special purpose keys. The video doorphone 140 shown in FIG. 7 is shown with only the minimum components for carrying out the present invention.
1, a control unit 142 that performs a control operation according to the output signal of the bell signal generation unit 141, a signal processing unit 143 that outputs an input signal under the control of the control unit 142, and a signal processing unit 1
A speaker 144 which outputs the signal processed by 43,
A video doorphone camera 145 configured to perform shooting operation under the control of the control unit 142 is configured.

The switch 713 for additionally selecting the output of the video doorphone camera 145 or the camera unit 15 and outputting it to the third input terminal X3 of the multiplexer 714 is the microcomputer 7.
The bell signal detector 116, which is connected to the bell signal generator 16 for controlling the bell signal, detects the bell signal.
41 and the microcomputer 716, and is interposed between the video signal processing unit 18 and the signal processing unit 1 of the video doorphone 140.
Read / write with 43 under the control of the microcomputer 716.
A memory 136 is connected to perform a write operation.

Here, since the display device is not generally configured at the entrance of the memory 136, it is sufficient that the memory 136 has a size enough to store an audio signal that can be output through the speaker 144. However, when the display device is configured at the entrance, the image signal and the audio signal are stored in the memory 136. The overall operation performed according to such a configuration is similar to that of the image telephone of FIG.

In FIG. 7, as shown in FIG. 6, functions required for automatic response include a function of outputting a message stored in the memory 136 in advance and a signal (visitor's message) input from the video doorphone camera 145. It is the function of storing. This will be described separately. First, when outputting a message stored in advance, the user may select a memory 136.
Prepare the recorded message for storage in.

The microcomputer 716 switches the control signal to the switch 71.
3 and outputs to the multiplexer 714 respectively, the output signal of the camera unit 15 is selected by the switch 713, and is output through the multiplexer 714. At this time, switch 7
The signal input through 13 is not an image signal but an audio signal input through a microphone (not shown) attached together with the camera.

Then, the above message is processed through the AGC 17 and the video signal processor 18 and written in the memory 136 under the control of the microcomputer 716. As a result, when the visitor activates the bell of the video doorphone, the bell signal is generated from the bell signal generator 140 and the controller 1
42 and the bell signal sensing unit 116, and the bell signal sensing unit 116 outputs the sensing signal to the microcomputer 716,
The microcomputer 716 outputs a read signal to the memory 136 and outputs the signal stored in the memory 136 to the signal processing unit 143.

Then, the control unit 142 controls the signal processing unit 143 to process the signal output from the memory 136 according to the input bell signal, and the video doorphone camera 1
45 is driven. The signal processed by the signal processor 143 is output through the speaker 144. Then, after the message is output through the speaker 144, the visitor's message (image and sound) is stored. This message is input by the video doorphone camera 143, passes through the switch 713 and the multiplexer 714, and then is sent to the AGC 17 and the video signal processing unit 18.
Signal processing is performed in accordance with the control of the microcomputer 716, and magnetic recording is performed via the recording control unit 19 and the head 20.

FIG. 8 is a flow chart showing a method of storing / outputting a message in the camera-integrated magnetic recording / reproducing apparatus shown in FIG. Here, the modes that can be performed by the message function that can be provided from the camera-integrated magnetic recording / reproducing apparatus are the message destination storage mode for storing the user's message, the message output mode for outputting the message stored in the memory, and the message output mode after the message output. It can be classified into a message recording mode for recording an input message on a magnetic recording medium.

Referring to FIG. 8, initialization and setup are performed in step S1 to select a function. In step S2, it is confirmed whether the selected function is the message function according to the selected function. If the selected function is the message function, step S3 is performed to check whether the message destination storage mode is set.
If the function confirmed in step S3 is the message storage mode, a state in which a private message can be recorded is set in step S31.

That is, the selection control signal AB is output as "HL" to the multiplexer 513 and the write control signal is output to the memory 130. A signal output from the camera unit 15 is selected by the multiplexer 513 and output to the video signal processing unit 18, and the signal processed by the video signal processing unit 18 is stored in the memory 130.

Accordingly, in step S32, the camera unit 15 is driven to store the message, and in step S33, the completion of storing the message is confirmed, and when the storage is completed, a message output waiting state such as a process drive state is waited in step S34. After setting the state, step S4 is performed. If the message storage mode is not set after performing S3 or S34, S4 is performed.
Perform the steps to check if the message output mode is set. If it is the message output mode, a message output standby state is set in step S5. At this time, the message output standby state means waiting for a signal from the call attempt detection unit 110 indicating that a call is being attempted.

After confirming the call attempt in step S6, step S7 is executed to output the message stored in the memory 130, and if it is not confirmed that the call output mode is canceled, it is determined in step S61. If the message output mode is not released, the process returns to step S6. S6
When the message output mode is released in one step, step S62 is performed to reset the initialization driving state S1 step,
It performs two stages (this is described below).

When the completion of the message output is confirmed in step S8 after performing step S7, the microcomputer 516 outputs the selection control signal AB of "HL" to the multiplexer 513 to output the signal output from the bidirectional telephone 100. Magnetic recording is performed through the video signal processing unit 18, the recording control unit 19, and the head 20. That is, the state in which the input message can be properly recorded is set.

When a message is input from the two-way transmitter 100, the message is stored in step S10, and step S11 is performed to check whether the storage is completed. If the storage is completed, step S12 is performed to check whether the message output mode is continuously performed. If the message output mode is continuously performed, the process returns to step S5.
After performing 13 steps, it is determined whether another function is performed. If another function is performed, the process returns to step S2. If not performed, the operation ends.

Therefore, when a two-way caller such as an image telephone or a video doorphone is connected to the camera-integrated magnetic recording / reproducing device to provide an automatic answering function, the user's message is stored in advance and output when a call is attempted. It is also possible to store messages left by the visitor or caller. Further, the present invention is not limited to an image telephone or a video doorphone according to the intention of the manufacturer, and can cover a two-way caller that can be connected to a camera-integrated magnetic recording / reproducing apparatus.

3 is output. Therefore, in the embodiment of FIG. 9, the comparison reference image is stored in the memory 204 in advance, and then the image stored in the memory 204 is compared with the image output from the camera unit 15 through the recording control unit 819 and the head 20. The input image is magnetically recorded, or a message including the image magnetically recorded in advance is sent to the head 22 and the reproduction control unit 821.
It is configured to be played through.

The operation will be described in detail according to the monitor mode and the message output mode which can be set in the microcomputer 816. The monitoring mode is to detect a moving object and capture an image of the detected moving object, and the message mode is to detect the moving object and output a message including a pre-stored image. First, the user should store the comparison reference image in order to perform the surveillance mode.

The image output from the camera unit 15 is input to the sampling unit 202 through the switch 201 by the control signal C1 of the microcomputer 816. The sampling unit 202 samples the input image. The reason for going through the sampling process is to reduce the amount of memory required for comparison with the minimum image data required for comparison. The sampled image is the A / D converter 203.
After being converted into a digital signal by, it is stored in the memory 204. At this time, the microcomputer 816 outputs a write control signal to control writing of data in the memory 204.

After storing the comparison reference image for such comparison, the microcomputer 81 is used to execute the monitoring mode.
6 outputs the selection control signal AB of'HL 'so that the output signal of the camera unit 15 is selectively output by the multiplexer 13 and the output signal of the camera unit 15 is switched to the switch 2
The signal is fed back to the sampling unit 202 via 01.

The sampling unit 202 samples the input image, and the A / D converter 203 converts the sampled image into a digital signal to output the first comparator 205.
To enter. On the other hand, the microcomputer 816 outputs a read control signal to the memory 204 so that the reference image signal previously sampled and stored in the memory 204 is output to the first comparator 205. As a result, the first comparator 205
The output image of the / D converter 203 is compared with the output image of the memory 104, and the difference signal resulting from the comparison is output to the low pass filter 206. After the low-pass filter 206 low-pass filters the difference signal, the comparator 207 compares it with a predetermined reference voltage (Vref), and the comparison result is input to the microcomputer 816.

The microcomputer 816 outputs the control signal C2 according to the output signal of the second comparator 207 to perform the recording operation. At this time, the image stored in the memory 204 and the image input through the camera unit 15 are input. If there is a difference, the recording operation is performed, and if there is no difference, the operation of comparing the input image with the stored image is continuously performed. Therefore, when a moving object is present in the predetermined space, the camera-integrated magnetic recording / reproducing apparatus recognizes this as an image and performs the monitoring mode.

In order to perform the message output mode of detecting a moving object and outputting a message, the output message should be stored in advance. That is, the user first records an image using the camera unit 15, and the message recorded in this way is input to the terminal X of the multiplexer 13.
3 is processed by the AGC 17 and the video signal processing unit 180 and output to the recording control unit 819 for magnetic recording.

After that, when the user sets the microcomputer 816 in the message output mode, the camera-integrated magnetic recording / reproducing apparatus senses the same moving body as in the monitoring mode. When the moving object is detected, the microcomputer 816 operates the reproduction control unit 821 by the control signal C3 to reproduce the message magnetically recorded in advance, and the reproduced message is reproduced by the video signal processing unit 18 and the video signal amplification unit 23. It is processed and displayed on a display such as a TV or monitor.

Therefore, a person who is detected as a moving body can confirm the message by outputting the message stored in advance. In FIG. 10, the image discrimination unit 20 of FIG.
Instead of 0, a motion sensor 210 is configured. The sensor device of the motion detector 210 may be an infrared sensor that detects infrared rays emitted from a moving body, an ultrasonic wave sensor, or an atmospheric sensor that detects the flow of the atmosphere according to the movement.

Here, the two modes described in FIG.
That is, the operations of the monitor mode and the message output mode are the same except that only a moving object is detected. That is, FIG.
Then, the image input to the camera unit 15 is discriminated and the moving body is detected, but in FIG. 10, the moving body is detected by a separate motion sensor. Referring to FIG. 10, the microcomputer 916 operates the motion detector 210 according to the user's mode operation, and then operates the motion detector 2.
A signal is recognized from 10 and the operation corresponding to the set mode is performed.

In the monitor mode, the motion sensor 21
When a motion detection signal from 0 is input to the microcomputer 916, the moving object photographed by the camera unit 15 is transferred to the multiplexer 1
3, the recording control unit 919 performs magnetic recording through the AGC 17 and the video signal processing unit 18, and in the message output mode, the motion detector 210 outputs a moving object detection signal to the microcomputer 91.
6, the reproduction control unit 921 causes the prestored message to be output as an image displayed on a display not shown via the video signal processing unit 18 and the video signal amplification unit 23.

FIG. 11 is a flowchart of a message storing / outputting method performed by the camera-integrated magnetic recording / reproducing apparatus shown in FIGS. 9 and 10. This process is roughly divided into three processes, which are composed of a moving image capturing process by driving a camera after detecting a moving object, a message output process and a message storing process stored after detecting a moving object.

In the CCTV mode in which the signal photographed through the remote camera is recorded in step S101, the function is selected in step S102, and the selected function is S103.
If it is determined that the function is the monitoring function at the stage, the moving body photographing process after detecting the moving body (S131 to S136) is performed. S10
If it is determined that the function is not the monitoring function in step 3, the current mode is determined to be the message output function and the stored message output process in step S104.

If the sensing function is determined in step S103,
The monitoring state is set in step S131. The monitoring state is to output a control signal for operating the image discriminator 100 or the motion detector 210 as the moving body detecting means in FIGS. 9 and 10. After performing S132, S1
In step 33, the operation corresponding to the presence of the moving body is performed. That is, if a moving object is detected, the camera unit 15 is driven and the signal of the camera 15 is selectively output in step S134.
The selection control signal AB is output to the multiplexer 13.
After the recording operation is started, steps S134 and S135 are repeatedly performed until there is no moving body. Steps S133 and S13
If a moving object is not detected in step 5, it is determined in step S136 whether to continue to perform the monitoring function. When the available monitoring function reservation time is completed, the monitoring function is stopped.

If there is a moving object detected in step S105 if there is a message output function in step S104, the reproduction controller is driven in step S107 to output the stored message. Steps S106 and S107
After performing step S108, it is determined whether the message output function is continuously performed in step S108, and if the message output function is continuously performed, step S105 is performed, and if the message output function is not performed continuously. The step S109 is performed. In operation S141, the operation of driving the camera unit and the recording controller S141 is performed, and then the operation of storing the message S142 and the operation S143 of confirming whether the message storage is completed are repeatedly performed to completely store the message. . Finally, in step S109, it is determined whether or not another function is selected.
Returning to step 02, the operation ends unless another function is selected.

Therefore, the message storage / output device of the camera-integrated magnetic recording / reproducing apparatus and the method thereof described with reference to FIGS. 9 to 11 outputs a message if the mode set by the user by detecting a moving object is the message mode. If the mode set by the user is the monitoring mode, the moving object is photographed.
